IMPROVEMENT IN DlTCHlNG-NIACHINES.

Bpecilication forming part-of Letters Patent N0. 142,222, dated August 26, 1873; application iiled June 27, 1873.

Be it known that I, JOHN W. FAUVER, of Augusta county, Virginia, have invented an Improvement in a Ditching-Machine; and I do hereby declare the following to be a full and correct description of the same, reference being had tothe accompanying drawings, in which- Figure 1 represents a side view 5 Fig. 2, an end view; Figs. 3 and 4, detailed views.

My invention relates to that class of ditchin g-machines in which a spade is attached to the rotating axle of a carriage by means of a axle the spade swings around and cuts a slice of earth from the ditch at the side of the carriage. My invention consists of one or more reversible spades located in the end of an arm projecting from the shaft of the driving-wheel of a carriage, said spade being reversed for the purpose of throwing the mud it contains back out of the way, and also toput it in po- My invention also consists in applying to said ditching-machine a means of throwing the spade and its operating mechanism. over outside of the line of the ditch,` in order to throw the mud and earth in the rear of the machine, and yet not back into the ditch, but upon the ground on the opposite side of the ditch from where the carriage is located.

Arepresents the drivin garde, upon th e outer end of which the spade-arm B isattached by a hinged connection, b. Y The shaft passes under the cams C and D, and is attached at the other end to the driving-wheel E, which may the speed. Upon the outer end of the spadearm is attached, by means of the slot c and shaft d, the spade-shank F, by which the spade is made to oscillate forward and backward, which will be more fully described hereafter. The spade G is constructed of solid metal, terminating in a sharp edge, and said V edge may be made of any shape desiredV to adapt it to thematerial'to be operated upon. 'Upon' the frame H, which supports the driving-shaft, is rigidly placed two or more cams, O and D, with cogs constructed upon their peripheries, as shown 5 and upon the spade-arm are several loose cog-wheels, I and K, which are arranged to engage the cogs on the cams. The cog-wheel I is a broad wheel, the width of the sum of the thickness of the cams C and D, and upon its shaft is placed a pulley, L, overwhich a chain-belt, M, passes, and upon the end of the shaft to which the shovel-shank is attached is another pulley, N, over which said chain-belt also passes. wheel I, and arranged to engage the cogs on the camV G, is a small loose cog-wheel, which, by also engaging the cogs on the cog-wheel I, reverses its motion.

The operation of my ditching-machine is as follows: Power being applied to the drivingshaft A by drawing the carriage forward, the spade-arm is made to move forward, carrying the spade with its edge forward, which spade is secured in this position by a stop-catch, O, Y

upon the side of the frame engaging a notch inside of the broad cog-wheel I, and preventing its revolution. While this catch is in this position the spade-edge is in position to enter the earth. The lower end of spring-catch P upon the outside of the spade-arm also rests V against the upper face of the driving-shaft to prevent the hinged spade-arm from moving outward, which may be seen at Fig. 3. The spade then enters the earth, being gaged to a proper depth by any of the known means of lengthening or shortening the spade-arm, one of which means is shown' in the drawings. The spade, on emerging from the ground lled with earth, is released from. its rigidity by a stop, Q, on thev frame, which releases the spring-catch O from its notch in the broad cogwheel I. The cogs of the small cog-wheel K immediately engage the cogs on the cam U, which, through the wheel I, chain-band M, and pulleys L and N, throw the spade backward to disen gage the earth from it. The spring-catch P is disengaged by means of a small cam, It, attached to theshaft of the cog-wheel I, thus allowing the spade-arm to be forced out laterally, in order to throw the dirt beyond the line of the ditch and behind the machine by means of an arm, S, upon the spade-arm, which travels over the inclined surface T of the sido of the cam G, an anti-friction wheel being placed upon the end of said arm S. A spring, V, acting against the outside of the spade-arm keeps the parte in gear. As the spade-arm Below said broad cog- 2 Magee passes forward the cogs of the broad wheel I engage the oogs on the cani D, and, by means of the chain-band and pulleys, the spade is again brought forward, and the catehesbrought into place, and the whole again prepared for another passage into the earth. Upon the frame H is placed another frame, W, which extends above the spade when it is in its highest position. Upon this second frame is placed over the spade a steel blade, X, which, by means of a spring, is made to pass over the face of the spade, and any earth which may remain in the spade is scraped out, and the Spade cleaned for its entrance into the earth.

A different means maybe used to remove the earth from the spade while it is in its reversed position, which may be operated by additional cams and pulleys; but this we do not elaini in this application.

Diggers may be geared to this apparatus to go in advance of the ditching-machine to loosen hard earth.

What I do claim, and desire to secure by Letters Patent, is-

l. The combination of the hinged spadearln B, spring,` V, arm S, and inclined surface T of the cam C, substantially as and for the purpose set forth.

2. The combination of the oscillating spade G, cams C and D, pulleys L and N, chain-band M, and wheels I and K, as set forth.

3. The combination, with the reversible spade G, of the spring-blade X, substantially as and for the purpose set forth.

The above specification of my said invention signed and witnessed at Washington, D. C. this 21st day of June, A.. D. 1873.
